Answer for screen readers
Melanie needs $13.71 more to complete her purchase.
Steps to Solve
- Calculate the cost of the flour
Melanie buys 2 pounds of flour at $4.49 per pound.
The total cost of the flour is:
$$ \text{Cost of flour} = 2 \times 4.49 = 8.98 $$
- Calculate the cost of the pie filling
She buys 6 cans of pie filling at $3.79 per can.
The total cost of the pie filling is:
$$ \text{Cost of pie filling} = 6 \times 3.79 = 22.74 $$
- Calculate the cost of the baking sheet
The cost of the baking sheet is given as $11.99.
- Calculate the total cost of all items
Now, add the costs of flour, pie filling, and the baking sheet:
$$ \text{Total cost} = 8.98 + 22.74 + 11.99 = 43.71 $$
- Calculate Melanie's total cash on hand
Melanie has a $20 bill and a $10 bill:
$$ \text{Total cash} = 20 + 10 = 30 $$
- Determine the additional money needed
Finally, calculate how much more money Melanie needs:
$$ \text{More money needed} = 43.71 - 30 = 13.71 $$
Melanie needs $13.71 more to complete her purchase.
